The following examples are used to illustrate the utility model, but cannot be used to limit the scope of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a multi-faceted grinding device for processing NdFeB magnets comprises a workbench 1, a transmission mechanism 2 is arranged on the workbench 1, a feeding mechanism 3, a first grinding mechanism 4, a flipping mechanism 5, a second grinding mechanism 6, a drying mechanism 7 and a feeding mechanism 8 are arranged on the transmission mechanism 2; the feeding mechanism 3 is used to transport the NdFeB magnets to the transmission mechanism 2; the first grinding mechanism 4 is used to grind the left and right sides of the NdFeB magnets on the transmission mechanism 2; the flipping mechanism 5 is used to flip the grounded NdFeB magnets by 90 degrees; the second grinding mechanism 6 is used to grind the two sides of the flipped NdFeB magnets; the drying mechanism 7 is used to dry the ground NdFeB magnets. The NdFeB magnets are formed; the unloading mechanism 8 is used to remove the dried NdFeB magnets from the transmission mechanism 2; when the NdFeB magnets that need to be polished are transported to the transmission mechanism 2 through the loading mechanism 3, they are transported to the first polishing mechanism 4 through the transmission mechanism 2 to polish the left and right sides of the NdFeB magnets, and after polishing, the NdFeB magnets are flipped 90 degrees through the flipping mechanism 5, and transported to the second polishing mechanism 6 through the transmission mechanism 2 to polish both sides, and after polishing, the surface of the NdFeB magnets is dried through the drying mechanism 7, and after drying, the NdFeB magnets are removed from the transmission mechanism 2 through the unloading mechanism 8 to proceed to the next process. Specifically, an efficient and automated NdFeB magnet processing multi-faceted grinding device realizes the full automation process from raw material loading to finished product unloading, greatly improves production efficiency, reduces human intervention, and thus ensures product consistency and quality stability. First, the working table 1 of the device is the core of the whole system. It carries the transmission mechanism 2 to ensure the stable transmission of the NdFeB magnets during the whole processing process. The transmission mechanism 2 is driven by a high-precision motor and is equipped with an intelligent control system, which can adjust the transmission speed and direction according to the processing needs. At the starting point of the transmission mechanism 2, the feeding mechanism 3 is responsible for automatically and accurately placing the NdFeB magnets to be processed on the transmission mechanism 2. The feeding mechanism 3 is equipped with an advanced visual recognition system, which can identify magnets of different specifications and shapes, and automatically adjust the feeding position and method to ensure that the magnets can smoothly enter the processing process. Next, the first grinding mechanism 4 grinds the left and right sides of the NdFeB magnets on the transmission mechanism 2. The mechanism uses a high-hardness, wear-resistant grinding tool, combined with advanced grinding technology, to ensure the smoothness and precision of the magnet surface. At the same time, the first grinding mechanism 4 is also equipped with an intelligent detection system, which can monitor the grinding effect in real time and automatically adjust the grinding parameters as needed. After completing the first grinding process, the flipping mechanism 5 flips the NdFeB magnet 90 degrees. The flipping mechanism 5 can ensure the stability and safety of the magnet during the flipping process. After the flipping is completed, the magnet enters the transmission mechanism 2 again and is transported to the second polishing mechanism 6 for double-sided polishing. The second polishing mechanism 6 is similar to the first polishing mechanism 4, but is aimed at the other two sides of the magnet. After the second polishing process, the surface quality of the magnet is further improved.At this time, the magnet is transported to the drying mechanism 7 for surface drying treatment. The drying mechanism 7 adopts an efficient hot air circulation system, which can quickly remove moisture and impurities on the surface of the magnet to ensure the dryness and cleanliness of the magnet. At the same time, the drying mechanism 7 is also equipped with an intelligent temperature control system, which can automatically adjust the drying temperature and time according to the material and thickness of the magnet. Finally, the unloading mechanism 8 automatically removes the dried NdFeB magnet from the transmission mechanism 2 and transports it to the next process for further processing. The unloading mechanism 8 is also equipped with an intelligent recognition system that can identify magnets of different specifications and shapes and automatically adjust the unloading position and method. The entire multi-faceted grinding device realizes the full automation processing from raw material loading to finished product unloading, greatly improving production efficiency and quality stability. At the same time, the device is also equipped with an intelligent control system and a monitoring system, which can monitor the equipment operation status and processing effect in real time to ensure the stability and reliability of the equipment.

[0024] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the flip mechanism 5 includes a rotating track 51 installed on the workbench 1, and the rotating track 51 is a twisted rotating pipe. Specifically, the flip mechanism 5 includes a rotating track 51 installed on the workbench 1, which is a carefully designed twisted rotating pipe. The twisted shape of the rotating track 51 ensures the stability and accuracy of the magnet during the flipping process. When the NdFeB magnet is transported to the position of the flip mechanism 5, it will be firmly fixed and then slide along the inside of the rotating track 51. The inner wall of the rotating track 51 is made of smooth and wear-resistant material to reduce the friction and wear of the magnet during the flipping process. At the same time, this material also has good guidance, which can ensure that the magnet flips according to the predetermined trajectory. This design greatly improves the accuracy and reliability of the flipping, and also ensures the position accuracy of the magnet after flipping. In addition, the rotating track 51 is also equipped with an intelligent control system that can monitor the flipping state and position of the magnet in real time, and automatically adjust the flipping speed and angle as needed. This intelligent control method enables the flip mechanism 5 to adapt to NdFeB magnets of different specifications and shapes, improving the flexibility and adaptability of the equipment. In summary, the flip mechanism 5, as a key component of the multi-surface grinding device, has a unique design and intelligent control method to ensure the stability and accuracy of the NdFeB magnet during the flipping process, providing a reliable basis for subsequent grinding. At the same time, this design also improves the automation level and production efficiency of the entire processing flow, and reduces the difficulty and cost of manual operation.

[0025] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the transmission mechanism 2 includes a first guide rail 21 and a second guide rail 22 arranged on the workbench 1, and the two ends of the rotating track 51 are connected to the first guide rail 21 and the second guide rail 22 respectively. Specifically, the transmission mechanism 2 mainly includes a first guide rail 21 and a second guide rail 22 arranged on the workbench 1. The first guide rail 21 and the second guide rail 22 are parallel and precisely aligned, providing a stable and reliable transmission path for the NdFeB magnet. The surfaces of the first guide rail 21 and the second guide rail 22 are made of wear-resistant and corrosion-resistant materials to ensure that high precision and smoothness can be maintained under long-term operation. The flip mechanism 5, as a key link in the entire processing flow, has two ends of its rotating track 51 connected to the first guide rail 21 and the second guide rail 22 respectively. When the NdFeB magnet is transmitted to the position of the flip mechanism 5 through the first guide rail 21, the NdFeB magnet flips 90 degrees along the rotating track 51. During the flipping process, due to the twisted design of the rotating track 51, the magnet can smoothly and stably complete the flipping action. After the flipping is completed, the NdFeB magnet is transferred to the second guide rail 22 to continue the subsequent processing flow. This design makes the entire transmission process seamless and greatly improves the processing efficiency. In addition, the transmission mechanism 2 is also equipped with an intelligent control system that can monitor the position and state of the magnet in real time and adjust the transmission speed and direction as needed. This intelligent control method makes the entire processing flow more flexible and efficient. In short, the synergy between the transmission mechanism 2 and the flipping mechanism 5 ensures the stable transmission and precise flipping of the NdFeB magnet throughout the entire processing flow. This design not only improves the processing efficiency, but also ensures the quality and consistency of the product.

[0026] Combination Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the feeding mechanism 3 includes a vibration plate 31 arranged on one side of the workbench 1, and the output end of the vibration plate 31 is fixedly connected to the first guide rail 21. Specifically, the feeding mechanism 3 includes a vibration plate 31 arranged on one side of the workbench 1. The vibration plate 31 is a common automatic feeding device, which arranges the NdFeB magnets neatly in a predetermined direction and speed by vibration, and transports them to a specified position. The output end of the vibration plate 31 is fixedly connected to the first guide rail 21, ensuring that the magnets can enter the transmission mechanism 2 smoothly and accurately. Under the action of the vibration plate 31, the NdFeB magnets are arranged in order and transported to the first guide rail 21. At this time, the transmission mechanism 2 starts to work and transmits the magnets forward along the first guide rail 21. Since the first guide rail 21 is tightly connected to the output end of the vibration plate 31, the magnets can smoothly transition to the transmission mechanism 2, avoiding collisions or damage that may occur during the transfer process. In addition, the vibration frequency and amplitude of the vibration plate 31 can be adjusted according to the size, weight and shape of the NdFeB magnet to ensure that the magnet can smoothly and stably enter the transmission mechanism 2. This flexibility enables the feeding mechanism 3 to adapt to NdFeB magnets of different specifications and types, improving the versatility and adaptability of the equipment. In general, the feeding mechanism 3 arranges the NdFeB magnets in an orderly manner through the vibration plate 31 and transports them to the transmission mechanism 2, providing a stable and reliable supply of raw materials for subsequent processing procedures. This design not only improves processing efficiency, but also ensures product quality and consistency.

Specifically, the first grinding mechanism 4 includes a first mounting frame 41 arranged above the first guide rail 21. This first mounting frame 41 is firmly fixed above the transmission mechanism 2 to ensure that it will not shift due to vibration or impact during the grinding process. The first mounting frame 41 not only provides a mounting platform for subsequent grinding components, but also ensures the precise alignment of the entire first grinding mechanism 4 with the transmission mechanism 2. A first cylinder 42 is arranged on the top of the first mounting frame 41. The first cylinder 42 is one of the power sources of the first grinding mechanism 4, and it controls the up and down movement of the first pressure plate 421 through telescopic movement. The function of the first pressing plate 421 is to fix the NdFeB magnet in place during the grinding process to prevent it from being displaced or rotated during the grinding process, thereby ensuring the accuracy of the grinding. Two first servo motors 43 are provided on both sides of the first mounting frame 41. The two first servo motors 43 respectively control the rotation of the two first grinding wheels 431. The first servo motor 43 has high-precision position control and speed regulation functions, which can ensure that the first grinding wheel 431 maintains a constant speed and stable force during the grinding process. The first grinding wheel 431 is the actual grinding component, which is made of wear-resistant material, has sufficient hardness and sharpness, and can effectively remove burrs and uneven parts on the surface of the NdFeB magnet. During the grinding process, the first servo motor 43 drives the first grinding wheel 431 to rotate, and the first cylinder 42 controls the first pressing plate 421 to fix the magnet in place, thereby achieving an accurate grinding effect. The entire first grinding mechanism 4 works in coordination with a precise mechanical structure and an intelligent control system to ensure the stability of the NdFeB magnet during transmission and the accuracy of grinding. This design not only improves processing efficiency, but also ensures product quality and consistency.

[0028] Combination Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the second grinding mechanism 6 includes a second mounting frame 61 arranged above the second guide rail 22, a second cylinder 62 is arranged on the top of the second mounting frame 61, a second pressure plate 621 is fixedly connected to the output end of the second cylinder 62, and a second servo motor 63 is arranged on both sides of the second mounting frame 61, and a second grinding wheel 631 is fixedly connected to the output end of the second servo motor 63. Specifically, the second grinding mechanism 6 includes a second mounting frame 61 arranged above the second guide rail 22. This second mounting frame 61 is also firmly fixed above the transmission mechanism 2 to ensure that it will not shift due to vibration or impact during the grinding process. The second mounting frame 61 not only provides a mounting platform for the subsequent second grinding assembly 6, but also ensures the precise alignment of the entire second grinding mechanism 6 with the transmission mechanism 2. A second cylinder 62 is arranged on the top of the second mounting frame 61. The second cylinder 62 serves as a power source and controls the up and down movement of the second pressure plate 621 through telescopic movement. The main function of the second pressing plate 621 is to fix the flipped NdFeB magnet in place during the grinding process to prevent it from being displaced or rotated during the grinding process, thereby ensuring the accuracy of the grinding. Two second servo motors 63 are provided on both sides of the second mounting frame 61. The two second servo motors 63 respectively control the rotation of the two second grinding wheels 631. The second servo motor 63 also has high-precision position control and speed regulation functions, which can ensure that the second grinding wheel 63 maintains a constant speed and stable strength during the grinding process. The second grinding wheel 631 is the actual grinding component, which is also made of wear-resistant material, has sufficient hardness and sharpness, and can effectively remove burrs and uneven parts on the surface of the NdFeB magnet after flipping. During the grinding process, the second servo motor 63 drives the second grinding wheel 631 to rotate, and the second cylinder 62 controls the second pressing plate 621 to fix the magnet in place, thereby achieving accurate grinding of the other two faces of the magnet. The entire second grinding mechanism 6 is similar to the first grinding mechanism 4 in design and function, but each is responsible for different grinding tasks. They work together to ensure that all surfaces of the NdFeB magnet can be accurately ground, improving the quality and consistency of the product. At the same time, this design also reflects the efficiency and automation level of the entire multi-faceted grinding device.

[0029] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the drying mechanism 7 includes a drum dryer 71 arranged above the second guide rail 22. Specifically, the drying mechanism 7 is responsible for removing the residual moisture or coolant on the surface of the magnet after grinding to ensure the dryness and cleanliness of the magnet. The following is a detailed structural and functional description of the drying mechanism 7. The drying mechanism 7 mainly includes a drum dryer 71 arranged above the second guide rail 22. The drum dryer 71 is an efficient drying device that generates heat through an internal heating element and evenly transfers the heat to the drum surface, thereby drying the passing NdFeB magnet. The drum portion of the drum dryer 71 is usually made of stainless steel or other corrosion-resistant materials to ensure good durability and stability during long-term use. Heating elements are provided inside the drum, and these heating elements can adjust the temperature as needed to meet the drying requirements of different materials and different process requirements. During the drying process, the ground NdFeB magnets are transmitted along the second guide rail 22 to the entrance of the drum dryer 71. After the magnet enters the drum, the drum starts to rotate and evenly distributes the magnet inside the drum. At the same time, the heating element starts to work, generates heat and transfers it to the magnet through the drum surface, evaporating the moisture or coolant on the magnet surface. The drum dryer 71 is also equipped with an intelligent control system that can monitor the temperature and humidity inside the drum in real time, and automatically adjust the working state of the heating element as needed to ensure that the magnet can reach the required degree of dryness in the shortest time. In addition, the drum dryer 71 also has an efficient exhaust system that can timely discharge the steam and exhaust gas generated during the drying process to keep the working environment clean and dry. In short, the drying mechanism 7 dries the polished NdFeB magnet through the drum dryer 71 to ensure the dryness and cleanliness of the magnet. This design not only improves the quality and consistency of the product, but also improves the efficiency of the entire processing flow. At the same time, the high efficiency and intelligent control of the drum dryer 71 also reflect the technical level and automation level of the entire multi-faceted grinding device.

Specifically, the unloading mechanism 8 mainly includes a unloading chute 81 arranged at the outlet of the second guide rail 22. The position of the unloading chute 81 is precisely aligned with the end point of the second guide rail 22 to ensure that the magnet processed by the multi-faceted grinding device can slide into it smoothly. The design of the unloading chute 81 takes into account the size and shape of the magnet to ensure that it can pass smoothly to avoid jamming or damage. Below the unloading chute 81, a collection frame 82 is arranged. The function of the collection frame 82 is to receive the magnets that slide off the unloading chute 81 and temporarily store them. The collection frame 82 usually has a certain capacity to accommodate a certain number of magnets and reduce the need for frequent replacement. At the same time, the bottom of the collection frame 82 is designed with a handle or wheel for easy carrying, which is convenient for the operator to move it to the next process or storage area. The design of the entire unloading mechanism 8 is simple and practical, which can ensure that the magnets can leave the working area in an orderly and safe manner after the processing is completed, avoiding interference with the working area and potential safety hazards. At the same time, the setting of the collection frame 82 also facilitates the collection and transportation of the magnets, and improves the efficiency of the entire processing flow. In summary, the unloading mechanism 8 plays an important role in the multi-faceted grinding device for NdFeB magnet processing. Through precise design and reasonable layout, it ensures that the magnets can leave the working area in an orderly and safe manner, providing a strong guarantee for the efficient operation of the entire processing flow.
